High electrical conduction of the Sb square net in an anti-ThCr₂Si₂ type La₂O₂Sb thin film grown by multilayer solid-phase epitaxy

Magnetotransport in an aluminum thin film on a GaAs substrate grown by molecular beam epitaxy

Magnetotransport measurements are performed on an aluminum thin film grown on a GaAs substrate. A crossover from electron- to hole-dominant transport can be inferred from both longitudinal resistivity and Hall resistivity with increasing the perpendicular magnetic field B. Also, phenomena of localization effects can be seen at low B. By analyzing the zero-field resistivity as a function of temp...

High-mobility thin InSb films grown by molecular beam epitaxy

The problem of preparing high-mobility thin InSb films is revisited for magnetoresistive and spintronic sensor applications. We introduce a growth process that significantly improves the electrical properties of thin unintentionally doped InSb layers ~60–300 nm! epitaxially grown on GaAs~100! substrates by reducing the density of dislocations within the interfacial layer. The epilayer propertie...

High-pressure Raman scattering of CdO thin films grown by metal-organic vapor phase epitaxy

modeling loss data by phase-type distribution

بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...

Electrical Conduction Mechanism in the High Temperatures for Thin-film Transistor Utilizing Tunnel Effect

The Tunneling-Dielectric TFT (TDTFT), that has thin dielectric films at both ends of the channel fabrication area, was fabricated with 1.7 nm SiNX film by LPCVD method. The conduction mechanism of the drain currents was examined in the temperatures from 293 to 623 K experimentally and theoretically. The Id-Vg characteristics were reproduced by the direct tunneling (DT) via SiNX film with an ass...
